Gauge for nipple cutters



GAUGE FOR NIPPLE CUTTERS Filed Aug 21 1935 Invenor '\m l v t]. 7 Z7a7ZZA Hamel Patented Oct. 13, 1936 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to a gauge for pipe or nipple cutter, the generalobject of the invention being to provide a graduated bar adapted to beconnected to the shank part of a cutter between the cutting jaws thereofwith an adjustable stop bar on the gauge bar which determines the lengthof pipe or nipple to be cut.

This invention also consists in certain other features of constructionand in the combination and arrangement of several parts, to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in which:-

Figure 1 is an elevation showing the invention applied to a cuttingtool.

Figure 2 is a front elevation of the device.

Figure 3 is a detail view of the sections of the graduated bar.

In these views the letter A indicates a cutting tool which may be ofhand or power type and which has the usual cutters a extending into thespace between the two jaws thereof.

In carrying out my invention I provide a graduated bar which is made upof sections I and I. Section I is provided at one end with a pin 6,which is adapted to loosely fit into the opening I of section I to joinsaid sections. One end of section I is threaded into a hole formed in aside of the shank of the tool slightly in front of the stationary jaw ofthe cutter, the section being held in place by a nut 2. Grooves 8 and 9are formed adjacent one of the ends of each section I and l respectivelyto receive the terminals of the coil spring I0. Accordingly, withsection I attached to the stationary jaw of the cutter, section I isadapted to be moved outwardly, and to be retracted to its normalposition, as shown in Figure 2, by the spring III.

A stop forming bar 3 has an enlargement 4 thereon which has a holepassing therethrough through which the section I of the graduated barpasses. A set screw 5 passes through the adjacent end of the bar 3,which has a threaded socket therein intersecting the opening on the bar,the inner end of the screw being pointed to engage any desired one ofthe row of countersunk depressions I I formed in the section I of thegraduated bar.

Thus when the device is in place the stop placed against the bar 3 andthen the pipe is cut.

To compensate for the thickness of the cutter in accurately cutting thework, a spring-pressed section I is provided on the graduated bar, whichis adapted to move outwardly as the thickness of the cutters increase.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claims.

What is claimed is:-

1. A gauge for cutting implements comprising a threaded member adaptedto be screw-threaded into the emplement, an elongated section providedwith a reduced extension, said threaded member having a bore therein forslidably receiving the reduced extension, 2. spring connection betweenthe threaded member and the elongated section, a slidable gauge memberon the elongated section, and means for fixing the slidable member indefinite positions on the elongated section.

2. A gauge for cutting implements comprising a threaded member adaptedto be screw-driven into the implement, an elongated section providedwith a reduced extension, said threaded member having a bore therein forslidably receiving the reduced extension, a spring connection betweenthe threaded member and the elongated section, a slidable gauge memberon the elongated section, and means for fixing the slidable member indefinite positions on the elongated section, said spring being of coiledconstruction, both said threaded member and elongated section beingprovided with a circumferential groove for receiving the correspondingend convolution of the spring, said spring being adapted to retain thethreaded member and elongated section in end to end abutting relation.
